Kirsty Wark must be traumatized, How did she survive this encounter without counselling
Broadcaster Kirsty Wark, who was a Celebrity MasterChef contestant in 2011, said he told "sexualised" jokes during filming.
Wark, who is best known for hosting BBC Newsnight, told BBC News that on two occasions, during early morning filming, Wallace told stories and jokes of a "sexualised nature" in front of contestants and crew.
She said she feels strongly that the comments were "really, really in the wrong place".
The presenter described her overall experience on the show as "joyous", adding that the team and crew were "fantastic". But she said: "The fly in the ointment, on occasion, was Gregg Wallace."
She added: "I think people were uncomfortable. We were essentially a captive audience. People looked embarrassed and just got on with their work.
"I was actually more angry than anything else, because I thought it was so inappropriate. And in a sense what I thought was it was about power more than anything else, that he felt he could."
